Objective: To compare patients with cystic fibrosis and healthy individuals in terms of their functional performance on the six-minute walk test (6MWT). Methods: A prospective, cross-sectional study involving healthy individuals and patients with cystic fibrosis treated at a referral university hospital in the city of Campinas, Brazil. The 6MWT was administered in accordance with the American Thoracic Society guidelines, and it was repeated after a 30-min rest period. For all of the participants, RR, HR, SpO 2 , and Borg scale scores were obtained. For the cystic fibrosis patients, nutritional status and spirometric values were determined. Patients with pulmonary exacerbation were excluded. Spearman's correlation coefficient and repeated measures ANOVA were used. Results: The cystic fibrosis group comprised 55 patients, and the control group comprised 185 healthy individuals. The mean ages were 12.2 ± 4.3 and 11.3 ± 4.3 years, respectively. The six-minute walk distance (6MWD) was significantly shorter in the cystic fibrosis group than in the control group for both tests (547.2 ± 80.6 m vs. 610.3 ± 53.4 m for the first and 552.2 ± 82.1 m vs. 616.2 ± 58.0 m for the second; p < 0.0001 for both). The 6MWD correlated with age, weight, and height only in the cystic fibrosis group. During the tests, SpO 2 remained stable, whereas HR and RR increased. Conclusions: In our sample, functional performance on the 6MWT was poorer among the cystic fibrosis patients than among the healthy controls in the same age bracket, and we found immediate repetition of the test to be unadvisable.Keywords: Cystic fibrosis; Exercise tolerance; Dyspnea. ResumoObjetivo: Comparar pacientes com fibrose cística e indivíduos saudáveis quanto ao desempenho funcional no teste de caminhada de seis minutos (TC6). Métodos: Estudo transversal e prospectivo, com indivíduos saudáveis e com fibrose cística de um hospital universitário de referência na cidade de Campinas (SP). O TC6 foi aplicado de acordo com as normas da American Thoracic Society e repetido após 30 min de repouso. Foram determinados FR, FC, SpO 2 e escore da escala de Borg em todos os participantes, assim como o status nutricional e valores espirométricos para os pacientes com fibrose cística. Excluíram-se pacientes em exacerbação pulmonar. Foram utilizados coeficientes de correlação de Spearman e ANOVA para medidas repetidas. Resultados: Foram incluídos 55 pacientes no grupo fibrose cística e 185 indivíduos saudáveis no grupo controle, com médias de idade de 12,2 ± 4,3 anos e 11,3 ± 4,3 anos, respectivamente. A distância percorrida no TC6 (DTC6) foi significativamente menor no grupo fibrose cística que no grupo controle em ambos os testes (547,2 ± 80,6 m vs. 610,3 ± 53,4 m no primeiro e 552,2 ± 82,1 m vs. 616,2 ± 58,0 m no segundo; p < 0,0001 para ambos). A DTC6 se correlacionou com idade, peso e altura somente no grupo fibrose cística. A SpO 2 manteve-se estável durante o teste, com aumento da FC e da FR. Conclusões: Nesta amostra, os pacientes com fibrose cística apresentaram u...

“…More vigorous exercise and severe forms of COPD can cause major reductions in SpO 2 and reduced exercise tolerance. (22,24) The self-reported sensation of dyspnea was greater in the control group than in the CF group. Healthy children might not have the ability to measure dyspnea, because this condition is unknown in their experience.…”

exercise testing oxygen uptake pulmonary hypertension ■ PURPOSE: To determine whether the 6-minute walk test (6MWT) is a predictor of peak oxygen uptake (Vo 2 ) in patients with idiopathic pulmonary arterial hypertension (IPAH).■ METHODS: A total of 157 patients treated for IPAH completed a 6MWT in accordance with American Thoracic Society standards. Heart rate, pulse oximetry, and Borg rating of perceived exertion were determined at baseline and posttest. A cardiopulmonary exercise test (CPET) was performed on a cycle ergometer using a ramp protocol. Participants were stratified post hoc by age into 3 groups: children (n = 26), adolescents (n = 49), and adults (n = 82). Multiple linear regression analysis was performed to predict peak Vo 2 from the 6MWT.■ RESULTS: The regression equation generated for the children was the only model to strongly predict peak Vo 2 (r = 0.87; P < .001). Similar models for adolescent (r = 0.59; P < .001) and adult groups (r = 0.68; P < .001) did not achieve the same level of correlation.■ CONCLUSION: Six-Minute Walk Test was able to accurately predict peak Vo 2 in children (6-12 years) with IPAH; however, the model was weaker for predicting peak Vo 2 in older populations. These findings suggest that 6MWT may be as valid a test for predicting peak Vo 2 in children with IPAH as CPET measured peak Vo 2 . In older IPAH populations, CPET is the only reliable method for the evaluation of peak Vo 2 . The cardiopulmonary response to exercise is an important clinical assessment tool, as it provides an integrated assessment of the respiratory, cardiac, and metabolic systems. The current gold standard method for assessing aerobic exercise response in humans is the maximum incremental cardiopulmonary exercise test (CPET). Peak V o 2 , measured by a CPET, has been widely used to assess functional capacity and predict survival in patients with advanced symptomatic heart failure and respiratory dysfunction. 1,2 However, CPET requires the use of expensive equipment and trained medical team supervision to conduct and evaluate each test. Submaximal tests, like the 6-minute walk test (6MWT), provide useful information on daily physical performance that are safe, simple, standardized, and inexpensive. The 6MWT offers a better estimation of daily living activities than other walk tests 3 and the American Thoracic Society has endorsed and published guidelines for performing the 6MWT in clinical settings. 4

Correlation between 6‐min walk test and exercise stress test in healthy children

Abstract: SMWT distance is significantly correlated with the eVO2 obtained during the EST. This indicates that SMWT is also one of the predictive markers for EST performance.
